Alpha pariah mission 2 bug

Finished mission 1 of alpha pariah where I freed klosterheim from a cage at the end, mission success screen showed as normal and it paused for 10 seconds when I finished the missiom then sent me straight to the bridge with no loot or xp, now I cant start the next campaign mission, investigation says rid martyr of nurgle warband but there's no quest marker or anyway to start the mission!!!
